- A new approach in synthesis of some telluro compounds
-
Aryl mercuric chloride (ArHgCl) undergoes transmetallation reaction with aryl tellurium chloride (ArTeCl3) to form diaryl tellurium chloride (Ar-TeCl2-Ar). This compound on further reduction forms diaryl telluroether or diaryl tellur

- TELLURADIAZAPHOSPHETIDINES: PREPARATION AND SPECTROSCOPIC CHARACTERIZATION OF THE PN2Te RING
-
The reactions of Ph2PN2(SiMe3)3 with ArTeCl3 (Ar = C6H5, C6H4OMe-4, mesityl) in acetonitrile at 23 deg C produce Ph2P(NSiMe3)2TeCl2Ar, which are formulated as four-membered rings on the basis of analytical and NMR (1H, 31P, 125Te) spectroscopic data. Key

- REACTIONS OF ACETYLACETONE WITH ORGANOTELLURIUM (IV) CHLORIDES-C1 BONDED ACETYLACETONATES OF TELLURIUM(IV)
-
The reactions of acetylacetone (AcAc) with ArTeCl3 (I), Ar2TeCl2 (II) and Ar3TeCl (III) (where Ar = phenyl, 4-hydroxyphenyl, 4-methoxyphenyl, 4-ethoxyphenyl, 3-methyl-4-hydroxyphenyl and 3,4-dihydroxyphenyl) have been investigated.The I gives ArTe(C5H7O2)Cl2 (IV) type derivatives but II and III do not react even on prolonged refluxing in the presence of anhydrous AlCl3.The structural features of the new acetonylacetone derivatives (IV) have been explored by IR, PMR, and CMR spectroscopy.The effect of phenyl ring substituents on the keto-enol tautomerism of IVhas been found to be minor.The bond formation between Te and C1 of AcAc and intramolecular secondary interaction between the oxygen of AcAc and Te have been inferred from spectral data.

- THE REACTIONS OF SELENIUM TETRACHLORIDE AND TELLURIUM TETRACHLORIDE WITH SOME TRIVALENT ARYL ORGANOMETALLIC HALIDES
-
The reactions of several trivalent organometallic aryl compounds with TeCl4 and SeCl4 were investigated.When diphenylboron bromide was treated with an equimolar quantity of tellurium tetrachloride in toluene, the phenyltellurium trihalide C6H5TeBr1.3Cl1.7 was obtained.The presence of the mixed halogens on tellurium can be explained in terms of a Lewis acid-base reaction between the boron and tellurium compounds.The reaction of diphenylboron bromide with selenium tetrachloride in toluene, produced mixed triarylselenonium chlorides.The presence of substituted toluenemolecules in the product is attributed to the reaction of selenium tetrachloride with toluene in the presence of the Lewis acid, boron trihalide.The reaction of triphenylaluminum with tellurium tetrachloride was found to produce triphenyl telluronium chloride.Both diphenylchloroarsine and diphenylchlorophosphine were oxidized from MIII to MV by either selenium or tellurium tetrachloride.The products were isolated as diphenylarsinic acid and diphenylphosphinic acid, respectively.
